Seeing the group barging in directly, Rocks' expression turned grim.
"Do you have no sense of propriety? How dare you enter my room without permission?"
Hearing this, the group couldn't help but break out in a cold sweat.
"We sensed signs of a battle from your direction during the banquet."
"So... we were a bit anxious and came straight in!" Wang Zhi stammered an explanation. However, he was inwardly complaining, "Since when does our pirate crew have rules like this?"
"Let this be the last time!"
"It's nothing serious. I was just having a discussion with Bob!"
"But since you're all here, I might as well teach you a lesson!" Rocks didn't give them a hard time. Since they were here, he might as well teach them something. At the same time, he wanted to show Bob that he indeed had the capability to teach him.
With that, Rocks walked out of the room. The others immediately followed.
In an open area, Rocks brought over a nearly two-meter-tall stone. He placed it in the center of the clearing.
The others gathered around.
Kaido also arrived at this time. He had actually woken up shortly after being carried back. But feeling too embarrassed to go to the banquet hall, he came straight here.
"Everyone knows that the three types of Haki are Armament Haki, Observation Haki, and Conqueror's Haki!"
At this moment, Rocks was very serious and stern. The commanders and crew members nearby all remained quiet, listening intently to Rocks' words.
It's worth noting that Rocks personally giving a lecture was an extremely rare occurrence. Many of the older crew members were seeing it for the first time. If they could glean something useful from it, their future training would not only be more efficient but also save a lot of time.
"Armament Haki can be seen as black iron armor; it can be applied to oneself or external objects, such as weapons." Rocks extended a finger, which turned black under the coverage of Armament Haki. "Besides the most basic hardening, the development and utilization of Armament Haki have deeper levels, such as wrapping and emission!"
"The next level is internal destruction, which in Wano Country is also known as the advanced Ryuou level!" As he explained, Red Haki began to swirl and flow around Rocks' blackened finger.
Bob immediately understood what Rocks was trying to do. He was imparting knowledge about Armament Haki to the crew. Some of the crew members who had been with Rocks for a long time clearly knew this. They were also listening attentively.
The newcomers, on the other hand, pricked up their ears, afraid of missing anything. They were all very nervous. Many of them had not yet awakened Armament Haki. They all hoped to gain some insights from this, to comprehend its mysteries later on.
Rocks, with his finger wrapped in red Haki, gently tapped the stone in front of him. The sound of the stone cracking was heard, but the surface of the stone remained intact. Everyone present couldn't help but widen their eyes.
Then, Rocks' finger made a swift motion. The two-meter-tall stone split into two halves, like a watermelon being cleaved in the middle. The interior of the stone was completely destroyed by the Haki, turning into a pile of powder.
"Is this... the advanced level the captain was talking about?"
"This is too terrifying!"
Destroying from the inside, Rocks' move left everyone present in awe. They were utterly shocked. It turns out that Conqueror's Haki can be used in this way. If one were to master this technique and lightly tap someone, wouldn't their internal organs turn into mush?
Some commanders couldn't help but be stunned when they saw this scene. They had only grasped a fraction of it. There was still a long way to go to reach the level of the captain. Only Whitebeard and Golden Lion seemed to fare slightly better, but they also wore solemn expressions.
From this, one could see the gap in strength compared to Rocks.
"Besides this, there is another technique, also a form of Haki, an advanced application of Conqueror's Haki!" As soon as these words were spoken, the entire room fell silent. Conqueror's Haki, a Haki that only one in a million could awaken. It couldn't be acquired through training.
The officers present were also surprised. Although they knew about it, and a few could use it, they hadn't expected Rocks to directly teach this technique.
This was one of the essential realms to become a top-tier powerhouse! Combined with the teaching of Armament Haki, people couldn't help but admire Rocks' magnanimity.
"Pay close attention. Conqueror's Haki is different from Armament Haki. It is a force of intimidation, but it can also be attached to attacks!"
With that, Rocks raised his fist, releasing a torrent of Conqueror's Haki. Some weaker pirates fainted on the spot. A glimmer of light flashed in Bob eyes.
Earlier in the room, Rocks had clearly held back. With a serious expression, Rocks threw a punch in the air towards a distant small peak.
Boom! A loud explosion echoed. The force of the wind scattered in all directions, and rocks flew everywhere. The small peak had completely vanished.
"What... what kind of power is this?" The pirates who witnessed this scene were filled with shock. Some captains could feel the terrifying force behind it.
If this punch had been directed at them, they would have been either dead or severely injured. Bob on the other hand stood to the side, deep in thought.
Then he turned to look at Bob position. With a grin, he said, "Bob demonstrate it again for everyone!"
